Alveolar hemorrhage (AH) is a heterogeneous clinical syndrome with a high mortality rate, characterized by extensive bleeding into the alveolar spaces. AH secondary to systemic thrombolysis treatment in the setting of acute myocardial infarction is an uncommon complication, but potentially fatal and can lead to acute respiratory failure. This entity is rarely reported in the literature. We report two cases of acute AH after intravenous thrombolysis for acute myocardial infarction, which could contribute to the literature on the subject, and discuss the risk factors as well as the clinical and radiological findings supporting the diagnosis. We overview also the rare previous published case reports in this context, and we contrast our findings with those reported in the literature.

Highlights Mediastinal and pericardial hydatid cysts are very rare even in endemic areas. Clinical features depend on the size and location of the cysts and involvement of neighboring structures. The diagnosis is based on ultra-sound examination, CT scan and serology. Cardiac MRI can provide interesting information in case of discrepancy between echocardiography and CT scan. The curative treatment of cardiac hydatidosis is above all surgical.

Introduction: An ever-growing number of patients with implantable cardiac rhythm devices are treated with radiation therapy for cancer and are therefore at risk of device failure. Several medical societies developed recommendations for the management of such patients. We report the case of a 76-year-old patient with an implanted cardioverter defibrillator, treated with external radiotherapy for breast cancer, to test in practice the recommendations on the management of similar cases.
